Patent EP-0415680-A1 (EP)
Inventor: ELKINS ROBERT BRUCE
IPC: G21C3/324
Filed: 1990-08-24
Abstract: An improved upper tie plate is disclosed in a fuel bundle for a boiling water nuclear reactor. The fuel bundle (F) includes an upper tie plate (U′), a lower tie plate, a matrix of sealed fuel rods (R′) supported therebetween, and a surrounding channel (C). Both the lower tie plate and the improved upper tie plate have two functions; they support the fuel rods in vertical upstanding relation between the tie plates and interior of the channel and permit the passage of moderating coolant through the channel from the bottom of the channel to the top of the channel. This moderating coolant enters through the lower tie plate in the liquid form, passes into the matrix of upstanding fuel rods where steam is generated and exits outwardly through the improved upper tie plate as a water steam mixture at the top or the fuel bundle. The improvement includes the support of the channel (C) directly from the fuel bundle lifting bail (B′) for transmission of load directly to the bail instead of a cantilevered support through the tie plate. This direct support enables reducing the direction of the matrix overlying the fuel rods for reduction of pressure drop in the escaping steam/water phase from the fuel bundle. Additionally, this alignment enables raising of the points of tie plate support for longer fuel rod length. Improved fuel bundle performance results.

Abstract: This method for determining the peeling energy of sandwiched sheet metal in a T geometry, having two outer leaves (2,3) of material, is characterised in that it consists in introducing this sheet metal into a traction machine (4,5) for peeling the leaves, in imposing a speed (V) of relative displacement determined at the ends of the leaves, in measuring a peeling force (F) necessary for obtaining this speed, when the force is stabilised, in measuring the maximum curvature ( theta  max) of the bend (6) at the level of the deformation of a leaf and in calculating the peeling energy (G) on the basis of these measurements while considering that the folding and unfolding energies of the leaves are equal. <IMAGE>

Abstract: Des procédés et des structures de conversion énergie/matière ont des applications diverses, y compris la génération d'énergie par fusion nucléaire contrôlée à une température relativement réduite, grâce à l'anéantissement sélectif des forces de Coulomb présentes dans les atomes matériels en fusion. L'anéantissement sélectif de l'énergie orbitale des électrons découle d'un nouveau modèle de l'atome, qui permet en outre d'obtenir des matériaux supraconducteurs par combinaison sélective de matière de façon à créer les conditions nécessaires à la supraconductivité. En outre, l'invention concerne l'absorption sélective d'énergie, telle que l'absorption de photons, et la création de matériaux additionnels selon le nouveau modèle de l'atome, qui surmonte les limitations des modèles antérieurs et est compatible avec des principes de base, tels que les équations de Maxwell.

IPC: A61K6/816
Filed: 1990-02-22
Abstract: The present invention relates to a method for the production of a chemically bonded ceramic product by a reaction between one or several pulverulent binding agents as well as a liquid reacting with said binding agents. The ceramic product can also include one or several aggregate materials, which essentially do not participate in the chemical hardening reactions. According to the invention a powder body is compacted, which comprises said binding agent(s) and possibly aggregate materials without an addition of said liquid, by subjecting, before said raw compact is impregnated with said liquid, said powder body to such a high external pressure that a thoroughly integrated raw compact is obtained, in which the filling density has increased to at least 1.3 times the initial filling density, which is defined as that filling density, which is obtained by shaking, vibrating and/or carefully packing the loose powder in a container.

IPC: B05B15/00
Filed: 1991-02-11
Abstract: Eine Schmiermittel-Suspension wird mittels einer Sprühdüse (4) intervallweise unter hohem Druck versprüht. Die Sprühdüse (4) arbeitet nach Art eines Ueberdruckventils, indem sie bei einem einen Schwellwertdruck überschreitenden Eingangsdruck der Suspension selbsttätig öffnet und bei Unterschreiten des Schwellwertdrucks selbsttätig schliesst. Die Suspension wird ohne Zwischenschaltung einer Absperreinrichtung direkt von einer pneumatisch angetriebenen Pumpe (2) zur Sprühdüse (4) gefördert. Der Pumpenausgangsdruck wird in den Pausen zwischen den Sprühintervallen auf einem Pausendruck gehalten, zum Versprühen der Flüssigkeit auf den Sprühdruck erhöht und am Ende des Sprühintervalls wieder auf den Pausendruck abgesenkt. Der Pausendruck ist dabei so bemessen, dass er gerade noch nicht zum Oeffnen der Sprühdüse (4) ausreicht. Durch die erfindungsgemässe Pumpendrucksteuerung erübrigt sich das bisher zwischen Pumpe und Sprühdüse erforderliche, der Abrasion unterliegende Absperrorgan, die Betriebssicherheit wird wesentlich erhöht und das Versprühen setzt ohne Verzug sofort bei der Erhöhung der Pumpendrucks ein. <IMAGE>

Abstract: The shim body (1) has plane and mutually parallel side faces (2), and its cross-section parallel to the side faces is essentially U-shaped. It is provided at opposite points on its side faces (2) with, on the plug side, a cylindrical projection (8, 9) and, on the socket side, a cylindrical recess. The generatrices of the recess are greater than twice the length of the generatrices of the projection. When two shims are brought together, the projection of the one shim and the recess of another shim together form a mating pair so that the projection of the one shim can be plugged, possibly with a force fit, into the recess of the other shim. Moreover, the projection on one shim can be pressed into the corresponding recess of the same shim. At least one channel or groove (30) running essentially at right angles to the side faces (2) may be provided on a narrow side of the shim body (1) in an outer region of a limb (5, 6) or central part (7) of the U-shape. <IMAGE>

Abstract: The object of the invention is to control the digestion in such a way that a desired pulp quality is available, as far as possible, simultaneously with the reaching of a preset digestion end point. A process control system is used for this purpose. This comprises first means which, for homogenising the starting conditions, follow up, in accordance with a set value, the quotient of the mass of at least one constituent of the digesting fluid, relative to the dry mass of wood in the digester, especially by replenishing with or stripping out at least one digesting fluid component, or by controlled draining of digesting fluid. Second means subject the digester to a pressure pulse, whereas third means avoid major temperature differences in the digester by acting on the circulation stream of the digesting fluid. Further, fourth means effect a presetting of the digesting temperature with the aid of a simulated pulp quality figure. Finally, fifth means can be provided which, at an unchanged digesting temperature, effect a fine adjustment of the digestion end point required to reach the pulp quality. For this purpose, the actual state of the digesting fluid is measured, especially by an extinction measurement, and/or the actual value of a pulp quality figure is measured. <IMAGE>

Abstract: A spindle motor for high speed hand tools is disclosed. The spindle motor includes a rotor (28) and a sleeve (21) that is journaled about the rotor (28). A pressure generating mechanism creates sufficient air pressure in a clearance (52) between the rotor (28) and the sleeve (21) to form a pressurized air film in the clearance (52) when the spindle motor is in normal operation. A plurality of armature coils (27) and a plurality of magnetic sensors (31) for detecting magnetism of magnetic poles in the rotor (28) are provided on the outer surface of the sleeve (21). The rotor (28) has a field magnet (13) with multiple magnetic poles. The sleeve (21) is formed of a ceramic material whose dielectric constant is 10 or lower. The pressurized air film created by the pressure generating mechanism is sufficient to radially supports the rotor (28) so that the rotor (28) does not significantly contact the sleeve (21) during normal operation of the spindle motor. The armature coils (27) cooperate with the field magnet (13) to rotate the rotor (28) by the magnetic interaction between magnetic fields formed by the armature coils (27) and the poles of the field magnet (13). The excitation of the armature coils (27) is controlled at least in part by signals provided by the magnetic sensors (31).
